Abstract (en)
[origin: WO0035619A1] A tool driver includes a housing (30) and a rotatable drive shaft (28). A chuck (10) for holding the tool includes a generally cylindrical body (12) having a nose section (80) and a tail section (82). Jaws (16) are slidably positioned in angularly disposed passageways (42) in the body (12). Each jaw (16) has a jaw face (34) and threads (36) formed thereon. A nut (18) is in operative communication with the drive shaft (28) so that the drive shaft (28) rotationally drives the nut (18). The nut (18) engages the jaw threads (36) so that rotation of the nut (18) moves the jaws (16) axially within the passageways (42). A locking mechanism (20, 48) is mounted to at least one of the housing (30) and the body (12) and is selectively actuatable to first and second operative positions. In the first position, the locking mechanism (20, 48) rotationally locks the housing (30) and the body (12) with respect to each other. In the second, it permits relative rotation between the body (12) and the housing (30).
